ing had to the accompanying drawings, in which- Figure 1 is a side elevation of a car con structed in accordance with and-embodying the invention. Fig. 2 is an end view of 'the same, the dotted lines indicating the positions the car-body will assume during the dumping operations. Fig. 3 is an enlarged vertical longitudinal section through a portionof the-sameon the dotted line 3 3 of Fig. 2. Fig. 4. is a side elevation of a modified form of car constructed in accordance with and embodying the invention, the modification Beit known that I,.THoMAs of the United States, and a residentof Jersey City, in the county of Hudson and State of New J ersey', have invented certain new and useful Improvements in Dumping-0ars, of which the following is a specification.

he invention relates to improvements in dumping-cars; and it. consists in the novel features of construction and combinations of parts hereinafter described and particularly, pointed out. in the claims.

The object of the invention is to produce a dumping-car of great. durability and extreme the entire car lacking complexity and being of such construction as 'to withstand severe usage.

In the car of my invention the frame of the truck is formed with upwardly-extending end sections provided with seats for trunnions secured to the ends of the car-body and provided also with runways leading upward from said seats and permitting the trunnions on the car-body to ascend therein during the dumping of said body. Thus when the'carbody is in a normal horizontal position the trunnions at its ends will rest within the seats provided for them at the ends of the'truckframe, and during the dumping of thecarbody the said trunnions will ascend along said runways, thus elevating the central portion of the car-body and permitting of the properdischarge of its contents from said body, the car-body during the dumping operation being thus enabled without being normally at a disadvantageous elevation to assume when turned on its trunn'ions for dumping the proper inclination to insure the discharge of its entire contents. The said. end sections furnish suitable surfaces to receive the ends of. the ear-body when the latter is dumped.

Another advantageous feature of the construction presented is that the car-body when dumped will be subjected to less strain and HILL, a citizen body-and the ends of the truck-frame; and

lines indicating the positions the car-body will assume during the dumping operations.

' In the drawings, 10 designates the truckframe, mounted upon usual wheels ll and having vertical end frames 12.12, which support the car-body 13, said car-bod y being-provided at its ends with the trunnions 14, adapted to the concave seats 15, formed centrally frames 12.

The car-body 13 (shown in Figs. 1 and 2) is of usual construction, except with respect to the tru'nnions 14, saidbody being of the usual rectangular outline and preferably formed with sides which are hinged at their upper edges, so that when said body is dumped the material carried may be readily discharged.

The ends 12 of the car-truck are .in the form of castings, and the inwardly-extending portions -or flanges of said endslinumbered 16) present curved surfaces extending belowthe ends of the car-body and adapted to receive the lower surfaces of the ends (if indicated by the dotted lines in Fig. 2. The upper surfaces of the flanges 16 of the ends 12 form curved surfaces, upon which the carbody 13 may have a rolling motion while being dumped or while turning from its horizontal to its inclined or discharging position and then back to its horizontal position, the said surfaces 16. allowing the car-body, withoutmaterial jan to itself, to roll gradually and easily while being turned to its dumping position instead of "being permitted to. turn downward with concussive force against the downward inclination of the car-body.

The nature of my invention and satisfactory means carrying the same into efiect will be fully understood from the detailed description hereinafter presented, reference beconsisting mainly as to the outline of the carv Figi5 is an'end 'view of same, the dotted;

and at the upper portion of the said end the car-body when the, latter is dumped, as

the truck-frame or some part con nected therewith. At the upper central portion of the ends 12 are formed the seats 15, hereinbefore referred to, for the trunnions 14, connected with the car-body, and at said upper portions of the ends 12 said ends are formed with the upward extensions '17, within which are formed the runways 18 18 for the trunnions 14, the said runways 18 diverging upward from the seats 15 and permitting the trunnions 14 to elevate under control when the car-body 13 is turnin downward laterally upon the supportirig-surfaces 16. Two runways 18 are employed, since it is desirable that the car body 13 be capable of being turned downward either to the right or left; but in any instance in which it is only desired that the car-body shall turn downward at one side of the truck-frame instead of at either side it will be necessary to employ but one of the runways 18, said one runway leading from the seat 15 and inclining upward and outward toward the side of the car at. which the carbody is intended to be dumped. 'lhe extensions 17., containing the runways 18, project upward at the ends of the car-body and are preferably closed at their outer sides, as shown, so as to as far as possible exclude dirt from entering space represented by the runways 18 and seat 15.

The truck-frame 10 throughout its main part will preferably be made in the form of an individual casting having the sides 19,between which, adjacent to the ends of the latter, are the ends 12, hereinbefore referred'to, and also the sections 20,which incline downward and inward from the ends 12 to the bearings for the axles 22, as indicated in Figs. 1 and 2. The lower portions of the downwardly and inwardly inclined sections 20 are in the form of arms their lower ends the upper half of the bearings for the car-axles 22, the lower half of said bearings being formed by the caps 23,01 usual forin,said caps 23 beingfastened to the arms 21 by means of usual screws. Thus the truck-frame throughout its main portion comprises the sides 19, the substantiallyvertical ends 12, and the downwardly and inwardly inclined sections 20, the said ends 12 having the surfaces 16 and also the extensions 17, containing the runways 18 for the trunnions 14. The truck-frame thus formed is entirely lacking in complexity and is of a simple and durable character. The invention isnot, however, in every instance limited to the down wardl yand inwardly inclined sections 20 of the truck-frame,since the more essential features of the frame. comprise the vertical ends 12, furnishing the surfaces 16 for the car-body,and the extensions 17, having the runways l8, and trunnion-seats 15.

When the car-body 13 is in a horizontal position,it should be sustained by some suitable means, and hence in Fig. 2 I illustrate the hooks and eyes 24,by-which the carebody within the 21, which constitute at may be maintained in a horizontal position during the travel of the car and which may be readily detached, so as to permit the carbody to tilt down ward for the purpose of discharging its load.

The car illustrated in Figs. 4 and 5 corresponds exactly with the car illustrated in Figs. 1 to 3, inclusive, except that the sides of the car-body, instead of being hing ed, as shown in Fig, 2, are, of hopper shape or curved, as indicated in Fig. 5, the shape of the car-body shown in Fig. 5 permitting of the discharge of the contents of said body Without providing said body with the hinged sides shown in Fig. 2. The form of the carbod y presented in Figs. 4 and 5 diflfering simply in outline from the car-bod y shown in Figs. 1 and 2 results in the minor changesin the truck-frame 10, the changes consisting mainly in giving the surfaces 16 of the ends 12 a slightly convex form, as shown in Fig.5, instead of theeoncave form indicated in Fig. 2, and in addition the runways 18 shown in Fig. 5 are more divergent than the runways of Fig. 2. In all other respects the truckframes .for both of the forms of cars illustrated are substantially identical with one another, and therefore the truck'frame of Figs. 4 and 5 will not require further specific description,since the description above given of the truck-frame shown in Figs. 1 and 2 applies to the truck-frame shown in Figs. 4 and 5. I present Figs. 4 and 5 merely to indicate that the invention is not limited to .the special form of ear-body illustrated in Figs. 1 and 2. The-essential features of the invention, therefore, comprise the ends 12 of the truck-frame, said endshaving the flanges 16 to receive the car-body when dumped and also having the extensions 17, provided with one or more runways for the trunnions14, carried by the car-body, the said runways permitting of the upward motion .of said trunnions during the downward tilting of the car-body.

It should be observed that the ends 12 extend upward a substantiald-istance and have the extensions 17 at their apex, whereby not only is a strong end frame 12 produced, but one which admits of thecimbody having a full movement with only a short travel of the tru unions 14, the result being thatduring the dumping of the car the trunnions 14 move so short adistance that they do not attain su flivcient momentum-to when arrested either become strained themselves or injure the extensions 17. The inwardly-extendingflanges 16 also form essential features of the and frames 12,and said flanges extend upward to the lower surface of the oar-body and afiord at their apex a seat for said body, while at the same time presenting regular surfaces on which the -body may roll downward and be supported during such movement. The surfaces presented by the flanges 16 oompel the full downward movement of the carbody after said body is once released and started, this being due to the fact that the said surfaces from their apex or point of contact wil h the car-body downward are on regular descending outlines, as shown, and of considerable declivity.

What I claim as-my invention, and desire to secure by Letters Patent, is

' 1. A dumping-car comprising the truck frame and car-body, the latter having the trunnions 14 at its ends, combined with the end frames 12 extending upward a substautial distance from the truck-frame and having the inwardly-extending flanges 16 and, at their apices, the seats 15.and upward extensions 17, said seats being provided to receive said trunnions and said extensions each containing a runway 18 for the ascent of said trunnions when said car-bodyis dumped,and said inwardly-extending flanges 16 being projected below the ends of the car-body and extending on regular lines from the apex of said end frames to the truck-frame for the support of the car-body during its dumping movement; substantially as set forth.

2. A dumping-car comprising the truckframe and car -body, the latter having the trnnnions l t at its ends, combined with the end frames 12 extending upward from the truck-"frame and having at opposite edges the inwardly-extending flanges 16 and, at their 30 apices, the seats 15 for said trnnnions and the upward extensions 17 each containing the upward ly-diverging runways 18 for said trunnions, the said inwardly-extending flanges 16 t'rame and car-body, the "latter having the trunnions at'its, ends, and said truck-frame comprising the ends having the inwardly-extending surfaces 16 and trunnion-seats 15, the extensions 17 containing the runways for said trunnions, the downwardly and inwardly inclinedsections 20 connecting with said ends and inclining to the bearings for the wheels. and sides connecting said ends; substantially as set forth.
